This paper analyzes preverbal overt subjects, comparing Brazilian Portuguese to (other) null-subject languages, especially within Romance. It explores syntactic and semantic properties, including resumption, ellipsis, quantifiers and scope, variable binding, ordering restrictions, pronominal distinctions, minimality violations, bare nouns and definiteness. It concludes that preverbal subjects in Brazilian Portuguese can be realized both in argumental positions (Specifier of the Inflectional or Tense Phrase) and non-argumental positions (Topic Phrase specifiers), with the possibility that both types of positions are filled by the subject in the same clause, incorporating properties that have been argued not to be found together in other languages.
